//  class  CBiasGainDlg
//
//  Author:     Harrison Ainsworth
//  Date:       05/99
//  Purpose:    be a dialog for inputing a bias/gain choice. to be owned and called from a 
//              CBiasGainGadget
//  Implemen-   DoWithParam() is supplied with a pointer to the owning gadget (in the OpParam), this 
//  tation:     is mainly used to tell the gadget when the dlg is running, which the gadget uses to 
//              ensure that only one (of its) dlgs is running at a time. So: you can have multiple of
//              these biasgain dialogs running, but each is used for a different purpose and is owned 
//              by a separate gadget.
